2-DIMENSIONAL CORRELATION OF SOLID-STATE AND LIQUID-STATE NMR USING A LASER TEMPERATURE-JUMP

Solid state NMR spectra and the corresponding liquid state spectra have been interrelated through two-dimensional experiments with a fast temperature jump during the mixing time. This jump must, as a minimum requirement, be shorter than the relevant spin lattice relaxation times, and was implemented using a CO2 laser heater. As the first demonstration of this experiment we report a 2D H-1 solid-liquid spectrum of camphor. Suggested applications of future 2D temperature jump experiments include studies of reversible chemical reactions, reorientational dynamics, phase behavior, and magnetic and electrical properties.
